TRIPPING MECHANISM FOR BINDERS.

Application filed September'24, 1924. Serial No. 739,742.

The object of my invention is to provide a tripping mechanism forbinders of simple, durable and comparatively inexpensive construction.

More particularly, my invention relates to an attachment adapted to besecured to the seat supporting pipe of a binder and operativelyconnected with the bundle carrier trip rod, whereby the attachment maybe operated when desired for mechanically operating the bundle carrierof a binder.

Still a further object is to provide a bell crank lever member adapted,when a foot lever is operated, to release the tripping mechanism forallowing the same to be operated from one of the moving parts of thebinder itself. 1

My present invention is an improvement over my patent on a carrieroperating mech-.

anism for binders No. 1,502,102, issued July 22, 1924.

With these and other objects in view, my invention consists in theconstruction arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of a seat supporting pipe of a binder withmy improved tripping mechanism for the bundle carrier thereof attachedto the seat supporting pipe.

Figure 2 is a vertical sectional view taken on line 22 of Figure 1.

Figure 3 is a top, plan view of the grain shield support, which issecured to the frame of my attachment.

Figure 4 is a detail, sectional view taken on line 4-4 of Figure 1showing the connection between a moving part of the binder and myattachment.

Figure 5 is a detail, sectional view taken on line 5-5 of Figure 1; and

Figure 6 is a detail view showing one of the drive shafts and the gearmounted thereon.

In the accompanying drawings, I have used the reference numeral 10 toindicate generally a seat supporting pipe of a binder.

The ordinary binder includes a grain elevator 11 operated from a shaft12 journall'ed in the frame 13 of the binder. In some ty es of bindersthe shaft 12 has a om.-

hine'd gear and sprocket 14 thereonwhich are driven from the tractionwheels of the binder for imparting rotation to the shaft 12 and thegrain conveyor 11.

My tripping mechanism is designed to be driven from the shaft 12 and Iprovide a pulley wheel 15 connected to a plate or the like 16, which isbolted to the spokes of the sprocket 14 by U-bolts 17 V The pulley wheel15 is provided with a flanged head 17 for retaining the belt 18 inplace. The belt 18 is used for driving my bundle carrier trippingmechanism, as will hereinafter be more fullydescribed.

My attachment includes a frame 19 in the form of a casting. The frame 19is connected to the seat supporting pipe 10 at its forward end by aU-bolt 20. The frame 19 has an outwardly extending flange 21 formed onone side, which is provided with a notch 22 having tapered sides forreceiving the seat sup-porting pipe 10, as clearly shown in Figure 2 ofthe drawings.

The rear end of the frame 19 has a slot 23 which receives a bolt 24therethrough for retaining the rear end of the frame to the seatsupporting pipe 10. The bolt 24 is ordinarily used for securing a footrest to the seat supporting pipe whereby the driver of the binder maystep upon the same in order to get the seat of the binder.

The ordinary foot rest is removed when my attachment is secured to thebinder, and in order to have a foot rest, I form the frame 19 with anenlarged foot rest portion 25, which is shown in Figure 3 of thedrawings.

The slot 23 permits the frame 19 to be secured to a seat supporting pipe10 of different sizes, the slot 23 compensating for any slightvariations.

The frame 19 has a pair of outwardly extending spaced ears 26 to whichare pivotally connected lugs 27 which have the grain shield support 28mounted therebetween which is ordinarily secured to the seat supportingpipe 10, and when my attachment is used, I mount the grain shieldsupport thereon.

The grain shield support 28 has an ordinary grain shield pivot bolt 29therein.

Adjustment of the grain shield support 28 may be accomplished bypositioning of the adjuster rod 30 in any of the openings 31 formed inthe enlarged portion 25 of the frame 19:.

The adjaster reel 30 is pivotally connected to a plate 32 secured to theouter free end of the grain shield, support 28,, all as clearly shown inFigure 3 mt the drawings.

The frame 19 has av pair of spaced bearings 33 formed thereon in whichare mounted a stub sl-i-a'lt 34. @ne end of the stub shatt Ellhas apulley wheel 35 fixed, thereto. around which the belt 18 extends. Thebelt 18 drives the shaft Fixed to the shaft 34 and spaced between thebearings 33. is a. gear 36.

The frame 19 also has a bearing 37 in. which is mounted a shaft 38.

A mutilated bevel gear 39 is keyed to the shaft 38 and. is adapted tomesh with the bevel pinionv or gear. 36. The bevel gear 35% which hasbeen referred to as a mutilated gear, has av number of teeth missingtherefrom so as to provide a blank space 40, shown in Figure, 2 of thedrawings.

The normal position of the bevel gear 39, is such, that the bevel pinionor gear 36 is. partially received. within the blank space 40.

On theback side of the 39 is formed an extension. or catch. lug 41,.

A bell; crank lever 42 pivotally connect edv to the frame 19 by means ofthe bolt 43. Gne part of the bell crank lever 42 is l provided with ahook 4d adapted to coact 42? of the lever 4-2 when the lever- 41-2 ismoved, as will hereinafter be more fiully set forth.

The lever 42 has fixed toit a. downwardly extending arm 46, A link 4? ispivotally connected tothelower end of the arm 46; and extends forwardlytherefrom and has its lorward end connected to a. bell crank lever 48mounted in a bearing 49,

One side of the bell crank lever 4C8 has a. foot pedal 59-there01r Theseat 51 rests upon a seat stand 52, which is fastened to thesupportingpipe 19.

The bell crank 4:8 is adapted to he operated by the foot of the driverorby the putt of. a rope in, case the binder is being pulled by atractor, in direction indicated by, thearrow 52 for causingthe link- 47;to operatealso. in the direction indicated by the ar row 52.

The forward movement of the link will cause the bell crank lever 49 toswingupon, its pivot to the position shown in dotted lines; in l igurel; of the drawings; for releasing the hook 4 1% from the extension 4 1and at the same time, the portion, 4:2 will strike the roller 45,;torcausing the gear 39to commence torotate.

The gear 89, when. started by being en.- gaged with the portion 42*,will; mesh with the; bevel pinion 36, thereby insuring the gear 39 to berotated one complete revolution from. power supplied from a movingpart 0the binder itself.

The ordinary binder is provided with a bundle trip rod 58, which isordinarily operated manually and in order to cause the bundle trip, rodto. operate from the gear 2-39., I insert one end of the rod 53 into asocket 5%. and lock; it the-rein by means of the set screws 55.

Thesockets 5d is pivot-ally connected to the gear 39;"tl'irough the bolt56. The bolt 56 mounted at a; point spaced away from the shaft 38 androtates in the path of a circle with the shaft 38 as its axis.

From the construction of: thepa-rts just described... it will be seen.that each time the gear 39' is permitted to rotate, it will cause thelJlll lCllHCBl'llQl' triprod 53 to.- be operated toroperating the.bundle carrier, which forms a part oil; thebinder itself.

In order to prevent the gear 39' front any possible backward movement. Lmount a pawl 57 on. the frame 19. and place a coil spring. 58 on a. bolt59 between the frame 19 and the pawl 571 The-pawl rests a, inst theunderside of the extension ll and pic vents any rearward or backward:rotation ot' the gear 39;

The bolt 59. limits the movement of: the pawl 57 in one direction.

In, order; to; insure the hook 4% to engage the extension. 411, Iconnect a coil. spring 60 totljie lower end oftrhe arm id and to an. arm(St on the frame 19;

The spring: 60 is connected to, the arm 4-6 through the medium ofa rod62;- which ex tends through the arm 46,. as clearly shown in Figure 5 ofthe drawings.-

The rod 62 is screw thi' eadod, asat (33, and slidably mounted withinan. opening (not shown) fornjied in the arm. (31 ot the trame 159.

.h ordcr'tolimit" the amount of swinging: movement ot the bell cranklever in either direct-ion 1' provide a. pair of steps (5 and (it) on:the rod 62 on eacl1.=side of the arm 61.

The stops (i l retain the bell crank lever 4:2 at one limitot'itsmorement and the stops 65lim-it the amoi 1t of; movement of thebell cranlii lever 42* in the opposite direction.

When the gear 39 has been operated, it will? cause the roller 45 tostrike against the curved surface o l the portion 42" and will ridethereorer.

The spring 60 will cause the hook member 44 ot the bell crank lever 4-2to be in its solid line position, as shown in Figure 1, where it will bein position to engage the extension orcateh 411-.

It Will-be seen from the foregoing that the gear 39 may be put' into,motionv by simply pushing the foot piece 50 otthe bell crank lever 48 inthe: direction indicated by the row 52 ll l The bell crank lever 42insures the releasing of the catch or extension 41, and at the same timecauses the gear 39 to be positively engaged for starting it so that itmeshes with the bevel pinion 36 and thereafter a complete revolution ishad for moving the bundle carrier trip rod 53 as necessary.

My attachment is very simple and can be quickly and easily connected toa binder and furnishes the necessary mechanism for operating andtripping the bundle carrier of the binder.

A guard 66 is secured to the frame 19 and extends over the gear 39.

Some changes may be made in the construction and arrangement of thevarious parts of my invention, without departing from the real spiritand purpose of my invention and its my intention to cover by my claims,any modified forms of structure or use of mechanical equivalents, whichmay be reasonably included within their scope.
